TRPV1 and TRPA1 Drive Nasal TSLP Production
2026-08-13
The reference study shows that TRPV1 and TRPA1 are present in nasal epithelial cells and connect channel activation to TSLP production through calcium-dependent NFAT signaling. Its combined imaging, pharmacological, gene-silencing, and calcium-chelation approach helps distinguish TSLP regulation from broader cytokine responses and provides a mechanistic framework for upper-airway inflammation research.
